STOP-BLOCK FOR HORSE-RAKES.

SPECIFICATION forming part of Letters Patent No. 269,515, dated December 26, 1882.

Application filed July 27, 1881. (X model.)

To all whom it may concern:

Be it known that I, REUBEN ELLWOOD, residing at Sycamore, in the county of De Kalb and State of Illinois,and a citizen of the United States, have invented new and useful Improvements in Stop-BlockstbrHorse-Rakes, ot'which the following is a full description, reference being had to the accompanying drawings, in which Figure 1 is a side elevation; Fig. 2, a top or plan view; Fig. 3, a cross-section on line 00 a: of Fig. 1; Fig. 4, a longitudinal section. Fig. 5 is a sectional view of a horse-rake, illustratin g my invention applied thereto.

This improvement is primarily designed to be applied to the horse-rake shown in my Pat ent No. 241,849, May 24,1881; but I do not limit its use to that particular rake, for it may be applied to any rake which has a stop-bar to limit or control the movements of the rakehead, whether such stop-baris connected above or below the rake-head.

The object of my invention is to provide a yielding stop or. stop-block for the stop-bar which limits or controls the movements of the rake-head as an entirety. This object I accomplish by the means illustrated in the accompanying drawings. A g

In the drawings, A indicates the section of the shaft, or of frame-work connected with the shafts or axle; B, a section of the stop-bar; G, the plate supporting the stop; a, the stop or stop-block; a, grooved ears or projections; b, spring-bolts through springs; d, projections to hold the springs in place; 0, look or stop for making the stop-block rigid f, bolt for fastening the plate 0; g, lugs or ears for limiting the backward movement of the stop-bar, and h a projection on the stop-bar to engage with the lugs g.

The plate 0 may, if desired, be cast with the lugs g, and the projection 61 may be detachable for the purpose of placing the stop-block in in proper position.

position from the front of the plate. The edges of the plate enter into grooves in the stop-.

block, (see Fig. 3,) and thereby hold it down The stop-block a is made of the form shown in Fig. 3, and is provided with the bolts 1), which pass through the ears d. The springs c are located around these bolts and between the stops (Z and stop block a, as shown, and

with this construction it is adapted to permit of the rake-head, as an entirety, passing easily over rough ground, and the springs are made sutiiciently rigid to prevent the rake-teeth from rising too high, or from remaining in any ele-' vated positionwhen forced up by any unevenness in the surface of the ground, and I do not limit the use of this part of my improvement to a use in combination with the stop 6; but for heat y or bunched hay on a smooth meadow it is desirable to make it rigid, and for this purpose I have applied the stop 6,

which, when it is swung out, as indicated by i the dotted lines in Fig. 2, in no way affects the yielding of the stop-block a, as it moves back and forth with it; but in the position shown by the full lines, and in Fig.4, the stop comes against thehead of the boltfand fills 7o 7 the space between said bolt and the stop-block, making it rigid or stationary, and the stop is so arranged that it can be thrown in or out by the toe of the operator, or otherwise, so that it may be changed from a yielding to a stationary stop, or vice versa, at will.

The head of the boltfforms the stop for the lock 6; but the stop may be otherwise formed, or the projection of the lock may be made to extend down to the projection 01 for a limit. The rear limit-stop, h, of the stop-bar B, as shown, is made a shoulder on the opposite sides of the bar; but a simple pin running through the bar B may be used instead of said shoulders, and a series of holes may be made, so that the position of such pin in reference to the lugs g may be changed.

I am aware that spring-teeth and separate springs for each tooth have been heretofore applied to horse-rakes, and I do not claim'go broadly the application of a spring to a horserake for easing the teeth in their passage over uneven surfacesorobstructions. Myimproved device is to be applied to the rake so that all v of the teeth attached to the rake-head may be moved and eased over obstructions and uneven parts of the ground, as an entirety, by the use .of asingle spring device.

What I claim as new, anddesire to secure by Letters. Patent, is-

1. In a horse hay-rake, the combination of the stationary plate 0, the yielding stop-block a, arranged to slide on said plate, and the stophar B, connected at one end with the rakehead, and having its other end arranged to rest against the yielding stop-block for limiting and controllingthe movement of the rake-head, i substantially as described.

2. In a horse hay-rake, the combination of 3. In a horse hay-rake, the combination of the stop-bar B, the springimpelled stop-block a, arranged to bear against the stop-bar and yield with its movements, the movable lock 6, and the stop f, said members being arranged the stop-bar B, the plate 0, the stop-block a, for operation to limit and control the movehaving the ears to, andarranged to restagainst ments of the rake-head, substantially as deihe end of the stop-bar, and the springs a, sus- I scribed. taining the stop-block, but permitting it to i REUBEN ELLWOOD.
